WATER-CLOSET VALVE.

SPECIFICA'IGN forming part of Letters Patent No. 274,628, dated March27, 1883,

Application tiled April 4, 1882.

To all whom it may concern Be it known that I, JOHN McGUIaE,of-1\iilwaukee, in the county of Milwaukee, and in the State of Wisconsin, haveinvented certain new and useful Improvements in (Jocks and Valves forWaterClosets, etc.; and I do hercby declare that the following is afull, clear,

and exact description thereof.

My invention relates to valves for waterclosets and draw-cocks, and willbe fully described hereinafter.

In the drawings, Figure'l is a side view ot' my improved water-closetvalve. Fig. 2 is a vertical longitudinalsection through thecenterthereof, on the line y y, Fig. 3, showing the valve open. Fig( 3is a transverse section taken on the line aux, Fig. l. Fighe shows myimproved valve applied to 'draw-cocks. Fig. 5 is a perspective view ofthe valve proper, and Fig. 6 is a side view of m v device and theoperating-levers of a water-closet.

A is the casting that forms the valve-chamber, and B is the valve. O isthe service-pipe, and D the delivery-pipe. E is a chamber, having anopening, a, that leads into the valve B, and another, c', that leadsinto the chamber back of the valve-head. F is a cog-segment by which thevalve is worked, its shaft F extending into a bearing, d, on one sideand out through a smiling-box, Gr, on the other, and having a flange,g2, vwhich bears against said box. This box has tapering sides and fitsin a collar, g, that has a correspondingly-tapered Inside of the box Iplace a suitable bushing, h, and over the collar g, I tit a cap, H, thathas an interior rim, g', that fits into the cap about the shaft, abushing, h', being also interposed between this rim g and the outer rimof the cap. v

The interior of myvalve B is open, so as to admit the water from theservice through it, and its rear end has one or more concaves, c, toadmit the water to the cup-leather valve c',

which allows water to rush past it when the valve is opened, but willnot allow it to flow back, and it can get out only through the aperturec; and to regulate its ow I screw a plug, e, into the chamber, and thisplug has a hole, e', entering its side at right angles to it, andjoining aneth er, c2, that enters its end, and the rapidity of this flowcan be regulated by (No model.)

make its aperture either full or partly open to the Vaperture af, thesaid plug c being screwthreaded on its exterior, so as to enable it tobe readily turned either way, whereby its transverse hole e' (which, asstated, communicates with its longitudinal hole e2, leading into thechamber E below the the valve-chamber) may either wholly or partiallycoincide with the described aperture a. and hence regulate at. any timethe amount ot water passing from the rear ot the valve-chamber throughthese pas sages a', e', and e2 into the chamber E, whence the watertindsits outlet from chamber E back into the valve through aperture a.

`The shaft F has keyed to its outer end a weighted arm, F2, and by it isturned when it is beingopened and closed; and when my valve is beingused for water-closets I provide the weighted lever F2 with a shortarm,f, that projects in front of its shaft F and carries a wheel,

j, and I provide the water-closet handle k with a lever, k', that hasalso a wheel, j', in its free arm, and this wheel is arranged to restupon the wheel j, so that when the handle is pulled up it will depressthe free arm of the lever and cause it in turn to depress the short armf of the lever F2, and, overcoming the weight W, turn the shaft F andopen the valve. Then as soon as the levers have been released the weightW, aided bythe head of water in the main, will begin to turn shaft Fback and close the valve as it expels the water from the rear ofthevalve-head into chamber E through aperture a' and plug E. When shaft Fis in place in the casting it passes through the stuffing-box G, which,resting upon its collar g2,

them, this opposing pressure being capable of regulation to determinethe length of time each valve shall permit the water to flow through it.

VThe operation of my valve is as follows: The opening of the valve is'accomplished by 1ifting the weighted arm of lever F2, (which is done,in the form of valve shown in Fig. 6, by

pulling up the handle 1:,which in turn, through pivoted lever la andwheel j', bears upon the wheel j and depresses the free end of thislever F2, as already described,) and this upward movement of theWeighted arm of said lever revolves the shaft F partially and causes thecog-segment F on said shaft to take into the rack ony the lower portionof theinterior of the valve Band open it against the pressure of theWater in pipe C, as shown in Fig. 2. The

' water will thenrush through past the-valvehead and through the valvelinto the deliverypipe D, While a small quantity forces itself.

past the cup-valve c' into the chamber beyond it. Now, when the Weightedarm ofthe lever F2 is released, it will begin to fall, and, aided bythe. pressure of water in pipe C, will .close the valve against thepressure of the Waterin the chamber behind the valve, Which must beexpelled through aperture a and passage e e2 in screw-plug e intochamber E before the valve can close, the said Water finding its Wayback to the valve through the aperture a, as hereinbefore fullydescribed.

What I claim as my invention, and desire to' secure by Letters Patent,is-

1. The valve-casting having seat d and tapering collarg, the taperingbox Gr,having packing h and h', and screw cap H, having interior rim,g', in combination with the shaft 1*",extending from the seat d entirelythrough the valve-chamber, box, and screw-cap, and having ange g2bearing against the end of box G, all substantially as set forth.

2. In 'combination with shaft F', the weighted lever F2, carrying awheel on its short arm, and the Water-closet lever havinga Wheel on itsarm adjacent to the short arm of lever F2, as set forth.

3. In combination with the valve-casting A, having longitudinalvalve-chamber, and the chambered and apertured castingE anditsperforated screwplug e, all communicating therewith, the valve B, havingeoncaves e, and cupleather valve c', substantially as shown anddescribed, and for the purposeset forth.

4. In combination with lthe casting A, having longitudinalvalve-chamber, the valve B, fitting snugly within the valve-chamber, andhaving an interior rack and concaves c to permit free Water-passage, andthe oog-segment F and shaft F', independent tapered box G, and screweap,through which said shaft passes, and suitable packing, all substantiallyas set forth. g

In testimony that I claim the foregoing I have hereunto set my hand, onthis 20th day of March, 1882, in the Vpresence of two witnesses.
